8 psi is standard boost (well 7psi is) so if it is chipped, etc then it won't be 8 psi.

Chipped, intercooler filter, hybrid & cam...should be around 190 BHP. Dump valve will not do anything for power except *maybe* make it quicker boosting...but a lot of people will disagree with this, so I'll not comment further otherwise it will just go off topic samcos will not make it quicker neither: but will handle more boost better than standard hoses & increases the looks.

If it's set up right: should be around the 190 - 200 mark....imo
